The Square Wave's innovative solenoid technology delivers a high-speed cycle rate that minimizes process variation for repeatable dot-to-dot consistency. A low actuation speed of 2 milliseconds prevents build-up of flux crystals on the valve's nozzle which could prevent the fluid from being deposited precisely on the bus bar. The pistons' unique material reduces friction and wear. Tests showed over 880 million cycles of use without any deterioration.

Because of its non-contact design, the Square Wave never touches the delicate and brittle PV wafer; therefore, breakage and rejects are minimized. A special nozzle enables multiple orifice diameters from 100 - 175 microns so deposit sizes and volumes can be easily changed.
